Find Sabstin V'Despth at 838, 133, -584 . Talk to her and she will aggro, 93^^^. Every 25% health she will summon a 93^^^ add that is best killed before you continue with her, or you will end up with all three adds on you.

While you don't have to clear the zone to do this quest, the Withered Guardian( 666, 128, -524 ) and Sawtooth the Corrupted783, 88, -600 are summoned during the encounter and you can save yourself some hassle if you kill them before speaking to Sabstin.

When Sabstin is dead, examine the flower at 816, 106, -603 .

Forgotten Pools: The second piece of the chalice is inside the red/blue tree room, towards the back under a tree at either -62, 36, -509 or -26, 39, -470 .

Crystal Caverns: Collapse: The third piece of the challice is at -70, 15, -74 , next to the alchemy table with the different colored potions.

Gather earth and air from the Plane of Growth:

Gather earth from the burial site of the Heartwood Master in Lesser Faydark at -733, 6, -332 .

Gather air from 10 wisps from Tenebrous Tangle. These are found on the tiny islands surrounding the larger islands in the zone. Just fly through the ones with green shinies.

Return to Firiona Vie.

She gives you a Druid's Divining Rod. Use at the Tree of Blight in Eastern Wastes( 642, -453, 4203 ) . When used, a 92^^^ Wetrot spawns - kill it. The update is no-trade, but seems to give a group update.
